Find LCM of 154,356,645,399,396 with Prime Factorization
| 2 | 154, 356, 645, 399, 396 |
| 2 | 77, 178, 645, 399, 198 |
| 3 | 77, 89, 645, 399, 99 |
| 7 | 77, 89, 215, 133, 33 |
| 11 | 11, 89, 215, 19, 33 |
| 1, 89, 215, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 1 x 89 x 215 x 19 x 3 = 1007802180
Therefore, the lowest common multiple of 154,356,645,399,396 is 1007802180.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
154 x 356 x 645 x 399 x 396 = 5587255285920
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
154 : 1, 2, 7, 11, 14, 22, 77, 154
356 : 1, 2, 4, 89, 178, 356
645 : 1, 3, 5, 15, 43, 129, 215, 645
399 : 1, 3, 7, 19, 21, 57, 133, 399
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,356,645,399,396, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
356:2x 2x 89
645:3x 5x 43
399:3x 7x 19
396:2x 2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 7x 11 = 5544
Therefore, the value for common factors is 5544.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 5587255285920/(1x5544)
LCM = 5587255285920/5544
LCM = 1007802180
Thus, we can understand that the LCM of 154,356,645,399,396 is 1007802180.
